I used to be a batboy at the Columbus Clippers Cooper stadium. I have been to a crap load of games when I was in high school.
No...its not really all that "major league". Its a very old stadium, oldest in the International league I believe. They are in line to get a new stadium located more downtown that will follow the traditional new stadiums.
The Clippers themselves are pretty abysmal this year. They are pretty much a bare shelf in terms of Yankees young talent.
